Mario Hernández announces retirement at 27 due to new injury

The 27-year-old Madrid-born defender, who debuted in La Liga with Rayo Vallecano, has announced his retirement after a career plagued by serious injuries.

Mario Hernández has announced his retirement from professional football at just 27 years old, citing a new injury as the final blow to a career marked by persistent physical problems.

The left-back's troubles began in September 2023 while at Real Oviedo, when he suffered an anterior cruciate ligament rupture requiring surgery. His recovery was complicated by meniscus issues, forcing a second operation in June 2024. He returned to training in late August 2024 but was unable to secure a new club after his contract with Oviedo expired.

Hernández came through Atlético Madrid's academy before developing at Rayo Vallecano's youth ranks. He made his La Liga debut on 13 September 2020 for Rayo against Mallorca, going on to make 37 appearances and score one goal for the Madrid club. After joining Oviedo in 2023, injuries derailed his career, and a fresh setback in November 2026 prompted his decision to retire.
